Derived count rate kcps
WebBecause the derived count rate is proportional to cr6 (c is the particle concentration and r is the particle size), it can be used to detect nanoparticle formation or degradation.29,30 After 0.5 h of incubation, the count rate dramatically decreased by almost 1 order of magnitude (from 47041 ± 702 to 5383 ± 43 kcps), revealing the decrease in WebMar 1, 2015 · Around a NECR of ∼35 kcps, the SNR 2 and slope values (in parentheses) are 22.57 (0.45 ± 0.06), 15.13 (0.25 ± 0.03) and 11.22 (0.18 ± 0.02) for Position A, B and C, respectively. However, the SNR 2 -NECR relationship of the NEMA phantom exhibits a quite different trend (slope: 0.04 ± 0.01).
